CHARLES COMSTOGK, OF INDIANAPOLIS, INDIANA.

JUMP-SEAT FOR VEHICLES.

SPECIFICATION forming part of Letters Application filed April 22, 1890.

To all whom it may concern.-

Be it known that 1, CHARLES COMSTOCK, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Jump-Seats forVehicles; andI do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in jump-seats for vehicles, theobject of the invention being to provide a jump-seat which shall besimple, durable, and cheap in construction, of sufficient length tooverreach the bed, to give greater seating capacity, and whereby thecushioned part may be folded up sufficiently to permit of its beingreadily turned over between the sides of the body and beneath the nextadjacent seat, as hereinafter clearly set forth.

IVith these objects in view my invention consists in the specialconstruction and in the combination and arrangement of the several partsof the jump-seat, substantially as hereinafter described and claimed.

Figure 1 represents in perspective a jumpseat constructedin accordancewith my invention, one end of said seat being shown as elevated to avertical position; Fig. 2, an end view, and Fig. 3 an enlargedperspective detail, of one of the extension-frames.

In the drawings, A represents the usual base-board or bottom of theseat, B the backsupporting standards, and (J the back, all of which maybe of any suitable construction,

' the standards B being preferably in two parts each and hinged as shownat b, Fig. 1.

The seat-bottom A, as shown, will be of a length slightly less than theinterior width of the body of the vehicle, and will be supported at eachend upon parallel legs D, pivoted to the seat-bottom, as clearly shownin Fig. and to the bottom of the vehicle-bed, such constructionpermitting the seat to be moved forward and downward, so as to rest uponthe bed-bottom in a horizontal position beneath the adjacent seat.

Pivoted at each end of the seat-bottom A Patent No. 449,095, dated March24, 1891.

$erial No. 349,017. (No model.)

full width of the seat-bottom, as clearlyshown in Fig. 2, is a U-shapedframe E, constructed,

U-end of which is preferably bent upward, as at 6 to form arm-rests atthe end of the seat. This frame is pivoted at the front and rear sidesof the seat-bottom, and is adapted to be swung upward to averticalposition and then over to the seat-bottom A, when it is desired to lowerthe seat, as shown in dotted lines, Fig. 2, and is made to extend, whenin its normal or horizontal position, considerably beyond the sides ofthe body, to thereby extend the seating capacity of the seat A. WVhen ina horizontal position, the U-shaped extension-frames E both' rest uponstops or projections 6 secured to the seat-bottom A, which stops supportthe frame. Each frame E is provided with a cross-bar e, which extendsfrom one to the other side of said frame, and to this cross-bar issecured the board to which the cushion is fastened. In order to bringthe top of the end cushions on a level with the cushion on the body ofthe seat, the cross-bars are projected down from the frame E adistancesufficient to allow for the thickness of the board and thecushion. This construction presents alevel unbroken surface which ismore comfortable to sit on and presents a more elegant appearance. Ifdesired, the cushion might be secured directly to the crossbar 2 Thesupporting-legs for the seat may be of any suitable construction, andtherefore I do not desire to limit myself to the construction shown inthe drawings.

The construction of jump-seat herein de scribed renders the vehicle towhich it is applied very convenient for travel for several reasons- 1 a,it gives greater seating capacity and more comfort than ordinaryjump-seats, the size of the seat being greatly increased, as beforedescribed, and it may be quickly folded up and placed beneath the seatin front, thereby leaving the rear portion of the vehicle-body free andunobstructed for the carrying of merchandise or other articles.

I claim- In a jump-seat for vehicles, the combinapreferably, from asingle piece of bar-iron, the

upon a pivot 6, extending, preferably, the

of the cushion, as shown, and the cushions to secured directly to saidcross-bars, substantially as described. V

In testimony whereof I alfix my signature in presence of two Witnesses.

CHARLES COMSTOCK.
